Carbide insert grades
GC1105
A TiAlN PVD coated fine-grain carbide with
good hot hardness and toughness pro-
perties. It is optimized for inserts with 95º
entering angle but is an all-round grade giv-
ing effective performance through FSM, ISM
and LSM areas.
The coating gives extremely good adhe-
sion which is required for lower feeds and
depths of cut. SGF is a ground insert with
sharp edges, this combined with GC1105
is outstanding in extreme finishing on vibra-
tion sensitive components with low feeds.
GC1115
A micro-grained carbide providing security
in more edge toughness demanding opera-
tions, e.g. reduce problems with notch wear
or chip hammering.
The PVD coating contains TiAlN for edge
line toughness as well as an aluminium
chromium oxide providing resistance
against built-up formation and crater wear.
A good balance of toughness and wear
resistance makes GC1115 ideal also for
more unstable conditions.
S05F
A CVD coated fine grain carbide with excel-
lent hot hardness properties. It is opti-
mized for applications with a 45º approach
(square, round, CoroCut RO and finishing).
The CVD coating provides an excellent heat
barrier allowing greater productivity and tool
life through ISM and LSM.
It is a grade for optimizing productivity
which does not allow for applications with
entering angles over 75º due to poor notch
wear resistance.
When in need of a more secure
solution, in more edge toughness
demanding operations.
When in need of more heat
and wear resistance at enter-
ing angles less than 75°.
When in need of more bulk
toughness or if an uncoated
grade is required.
